Abstract A yellow pigmented bacterium designated strain $ MBLN094^{T} $ within the family Flavobacteriaceae was isolated from a halophyte Salicornia europaea on the coast of the Yellow Sea. This strain was a Gram-stain negative, aerobic, non-spore forming, rod-shaped bacterium. Phylogenetic analysis of the 16S rRNA gene sequence of strain $ MBLN094^{T} $ was found to be related to the genus Zunongwangia, exhibiting 16S rRNA gene sequence similarity values of 97.0, 96.8, 96.4, and 96.3% to Zunongwangia mangrovi $ P2E16^{T} $, Z. profunda SM-$ A87^{T} $, Z. atlantica 22II14-$ 10F7^{T} $, and Z. endophytica $ CPA58^{T} $, respectively. Strain $ MBLN094^{T} $ grew at 20‒37°C (optimum, 25‒30°C), at pH 6.0‒10.0 (optimum, 7.0‒8.0), and with 0.5‒15.0% (w/v) NaCl (optimum, 2.0‒5.0%). Menaquinone MK-6 was the sole respiratory quinone. The polar lipids were phosphatidylethanolamine, two unidentified aminolipids, and four unidentified lipids. Major fatty acids were iso-$ C_{17:0} $ 3-OH, summed feature 3 ($ C_{16:1} $ω6c and/or C16:1 ω7c), and iso-$ C_{15:0} $. The genomic DNA G + C content was 37.4 mol%. Based on these polyphasic taxonomic data, strain $ MBLN094^{T} $ is considered to represent a novel species of the genus Zunongwangia, for which the name Zunongwangia flava sp. nov. is proposed. The type strain is $ MBLN094^{T} $ (= KCTC $ 62279^{T} $ = JCM $ 32262^{T} $). Ausführliche Beschreibung
